Outline of Final Research Achievements

We have found the important role of O 2p hole in the Li-ion battery cathode material Li cobaltite by means of O 1s x-ray absorption spectroscopy. We have revealed the nature of stripe-type charge-orbital order of Ir 5d and Te 5p holes in a triangular lattice Ir telluride. We have also have investigated the relationship between the strong spin-orbit interaction and the multi-band Fermi surface in the superconducting phase obtained by suppressing the charge-orbital ordering in the Ir telluride. We have studied the relationship between the Fe 3d/Bi 6p orbital degeneracy and the inhomogeneous electronic states in the square lattice Fe chalcogenide/Bi chalcogenide superconductors by means of angle-resolved photoemission spectroscopy and x-ray absorption spectroscopy.
